Thanks for the tip!  I think that should work, though I'd like a more
notmuch-ish solution if possible.  And in fact I had some success on
advising `notmuch-mua-mail' and reacting on 'From from `other-headers'.

I wonder whether notmuch may consider adding an abnormal hook that pass
in `headers' as an argument so that we don't need to use an advice?
